Module 1 Kinematics
Relative Velocity
SUVAT
v = u + at
v^2 = u^2 + 2as
s = ut + 1/2at^2
Values
u
a
v
s
t
displacement (m)
initial velocity
final velocity
acceleration
time (s)
Scalar vs Vector
Vector
Scalar
Magnitude and Direction
Magnitude no Direction
Speed
Distance
Velocity relative to an observer
What velocity would appear to be if observer assumed stationary
V a +- V b = V b rel a
Motion on a Plane
Vector triangles to cancel out multiple vectors
